The Vent Tile is designed to maintain a 10,000 mm² of airflow whilst channelling any water ingress out of the vent and on to the roof covering.
In-line and discreet low profile design
Integral sidelock clip to ensure secure fit.
Profile suits all top tile manufacturers (Marley Mendip, Redland Grovebury, Russell Pennine and many more)
Fully independently wind tunnel tested
